Description (last modified by shorowit)

Per email exchange with David Beal, add a second location and fraction for ducts. For example,

Location: Attic
Location Fraction: 0.7
Location 2: Crawlspace
Location 2: Fraction 0.1

...and the remaining 20% would be in conditioned space.

We should also clarify that the fractions only apply to supply ductwork, and that 100% of the return ducts and air handler are assumed to be in Location 1.

Would it be worthwhile to have a separate location fraction for return ducts? That would have helped Phil Kerrigan's case, but seems not worth it since default return duct leakage is only 1% whereas return AH leakage is 4%.
